- lfs_cksum.c doesn't actually need ulfs_inode.h any more.
- neither does lfs_itimes.c.
- add hacks to fsck_lfs to make it compile.
- add hacks to newfs_lfs to make it compile.
- fix warning in ulfs_quota.c when quotas are fully disabled
(as I guess is happening with the rumpity version)
XXX: This commit adds -I${NETBSDSRCDIR}/sys to the Makefiles for
XXX: fsck_lfs, newfs_lfs, and lfs_cleanerd. This needs to be cleaned
XXX: up ASAP; but I consider this less problematic in the short term
XXX: than spewing ulfs_*.h into /usr/include.
pollution. Specifically:
ROOTINO -> UFS_ROOTINO
WINO -> UFS_WINO
NXADDR -> UFS_NXADDR
NDADDR -> UFS_NDADDR
NIADDR -> UFS_NIADDR
MAXSYMLINKLEN -> UFS_MAXSYMLINKLEN
MAXSYMLINKLEN_UFS[12] -> UFS[12]_MAXSYMLINKLEN (for consistency)
Sort out ext2fs's misuse of NDADDR and NIADDR; fortunately, these have
the same values in ext2fs and ffs.
No functional change intended.
the main loop. This is useful for very quickly executed lfs runs
such as those in tests, as an initialization phase cleaner may
prevent file system unmount.

Make it possible to run the lfs cleaner in a library fashion (taking
the quick route with the implementation).
run through copy-on-write. Call fscow_run() with valid data where possible.
The LP_UFSCOW hack is no longer needed to protect ffs_copyonwrite() against
endless recursion.
- Add a flag B_MODIFY to bread(), breada() and breadn(). If set the caller
intends to modify the buffer returned.
- Always run copy-on-write on buffers returned from ffs_balloc().
- Add new function ffs_getblk() that gets a buffer, assigns a new blkno,
may clear the buffer and runs copy-on-write. Process possible errors
from getblk() or fscow_run(). Part of PR kern/38664.

While touching all vptofh/fhtovp functions, get rid of VFS_MAXFIDSIZ,

Note that if two blocks have the same inode and block number, they sort
the same (this should never happen, but if it does there's no reason to
have qsort scramble the list).
Add some diagnostic syslog messages for unusual cases.
In determining when to stop reading segments when counting bytes (-b flag),
total the sizes of the blocks we're actually writing instead of assuming
they are all full blocks: many could be fragments or inode blocks. This
increases the number of segments per Ifile write, markedly improving the
efficiency of the cleaner in the small file case.

than NDADDR (which do not use indirect blocks).
Also, note the loss of only half a block per segment to fragmentation
when considering the benefit function, rather than a whole block.
